Relative Ages Activity

Which of your two friends is older? To answer this question, you’d need to know their relative

ages. You wouldn’t need to know the exact age of either of your friends – just who was born

first. The same is sometimes true for rock layers.

What You’ll Investigate

Can you determine the relative ages of rock layers?

Procedure

1. Analyze Figures A and B.

2. On Figure A below, identify the

relative age of each rock layer,

igneous intrusion, fault, and

unconformity. For example, the

shale layer is the oldest, so

mark it with a 1. Mark the next-

oldest feature with a 2, and so

on. (5 pts)

3. Repeat step 2 for Figure B. (5

pts)

Sedimentary Rock Metamorphic Rock

Magma Sediments

Directions: Label the arrows with the process that changes one rock type to another. In a paragraph explain how minerals originally in magma could travel through the cycle and

eventually end up in each of the three main classifications of rocks.

Rock Cycle Lab

Purpose: To simulate the changes that occur during the rock cycle.

Materials (per partnership): Procedures:

1. Examine the sugar cube with a hand lens. How is the sugar cube like a sedimentary rock?

_________________________________________________________________________________________________________

2. Crush the sugar cube into a powder. What part of the rock cycle does this represent? Explain in

words and draw a labeled diagram below.

_________________________________________________________________________________________________________

3. Make a “boat” with your foil. Pour the crushed sugar into the foil boat. What part of the rock cycle

does this movement represent? Explain in words and draw a labeled diagram below.

_________________________________________________________________________________________________________

4. Carefully put the “boat” over the candle flame. Observe as the sugar begins to melt. What part of

the rock cycle does this represent? Explain in words and draw a labeled diagram below.

_________________________________________________________________________________________________________

5. Set the foil “boat” away from the flame and wait 2-3 minutes. What happened to the melted sugar?

What part of the rock cycle does this represent? Explain in words and draw a labeled diagram

below. __________________________________________________________________________________________________

6. Break the hardened sugar into pieces. What part of the rock cycle does this represent? Explain in

words and draw a labeled diagram below. _____________________________________________________________
